transient outward\((I_{to})\)  , rapid delayed rectifier\((I_{Kr})\)  and slow delayed rectifier \((I_{Ks})\) , and inward rectifier
currents \((I_{K1})\) , \(I_{NaCa}\)  is \(Na/Ca^{2+}\)  exchange current, \(I_{NaK}\)  is \(Na/K^{+}\)  pump current, \(I_{pCa}\)  and \(I_{pK}\)  are
plateau \(Ca^{2+}\)  and \(K^+\)  currents, \(I_{bCa}\)  and \(I_{bK}\)  are background
\(Ca^{2+}\)  and \(K^+\)  currents and \(I_{KATP}\)  is the\( K_{ATP}\)  current, all are modeled as in [1]}, \(I_{KATP}\)  which accounts for
